    摘要： A method for the reactivation of aged chromia-alumina dehydrogenation catalyst which involves doping the aged catalyst with minor amounts of zinc oxide, preferably in the range of about 0.35% zinc oxide to 1.35% zinc oxide on the catalyst. The zinc oxide is added to the aged catalyst preferably by impregnation by immersion or spraying of a zinc nitrate solution, followed by drying and heat treating. Alternatively the zinc oxide addition can be accomplished by use of a volatile organic zinc compound added to the saturated feedstock and subsequent air regeneration of the catalyst in situ without removal of the catalyst from the reactor.

    摘要： This invention relates to an improvement in the vapor phase catalytic production of an amine by the reaction of a mixture comprising a C 2-4 olefin and ammonia. The improvement which provides for high conversion and selectivity to the amine resides in the use of an acidic offretite as the catalyst.
